How do dolphins greet each other? They wave.
Well... that’s not technically true, at least for Common Bottlenose Dolphins (Tursiops truncatus). They greet each other with a signature whistle!
This is their own unique call, which they use to communicate with other dolphins throughout their life, like announcing their name.
They have a great memory for each other’s whistles. Researchers found Common Bottlenose Dolphins can recognise each other even 20 years after the last time they heard the call!
